I have to solve a depreciation problem I am not sure how to do this I have found the slope it is -6000 the coordinates of two points on the graph I have picked are (1.0,108000)and (2.0, 114000)the cost of the printing press in the year 2006 120,000. the graph shows the depreciation in 6month intervales

\n" ); document.write( "Comment: The slope is the change in y for each change of one in x.
\n" ); document.write( "Your x changes one, but your y value has increased. That is not a
\n" ); document.write( "decreasing function.
\n" ); document.write( "---
\n" ); document.write( "Are you sure you are not supposed to use an exponential function
\n" ); document.write( "to show your depreciation?
\n" ); document.write( "---
\n" ); document.write( "For example, if \"y\" decreases 8% each 5 years you
\n" ); document.write( "could use y = P(0.92)^(t/5) where t is the time in years
\n" ); document.write( "and P is the original value of a house.
